To (1% whom it may concern:

Be it known that 1, JAMES A. GRAHAM, of 1 Milwaukee, in the county ofMilwaukee, and 3 in the State of Wisconsin, have invented cer- 5 tainnew and useful Improvements in Binder- Shifter Mechanism; and I dohereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates to harvesters and binders; and it consists inimproved mechanisin for shifting the binder, which will beelevator-frame B, and adjacent to its lower front edge the saidbinder-deck is secured to 2 5 the upper end of an arm, I), which arm issecured to and projects up from the gas-pipe O, that forms part of thebinder-frame, the said upper end of said arm 1) being preferably shapedto receive and be attached to a strengthening-strip, 19, secured to theunder side of said binder-deck. The lower portion of the binder-deck;from about its center to its rear edge rests upon and is secured to thebinder-frame in the usual manner. This gaspipe C is supported near therear end of the harvester by braces (I d, that project from thecross-truss l') l) of the liarvester-lrame, the two braces (l dintersecting to form a loose bearing forthc gas-pipe to slide in 5 andat its opposite end this gas-pipe is supported in a bearing, c, in astandard, 1", that projects up from an arm, g, on the lower frontstubble corner of the harvcstcrframe, and this standard is braced by astrap, 9, to the truss D, as well as by a rod, 71, that extends fromnear its upper end to the upper portion of the elevator-frame, as shownclearly in Fig.

E is a hood, preferably of sheet metal, that is secured at one edge tothe upper portion of the ele\-*ator-frame, so that its opposite edgewill project over the binder-deck toward the standardF and arm G of thebinder-frame, which carry the knot-ter-shaft H.

A gas-pipe, I, is rigidly suspended between thehood E and sleeve G, andparallel to them, by a brace, '2', that extends from one end of thesaidgas-pipe to the standard F and braces 70 k that extend from said as- )lre to sleeve J a l l.

G, and this pipe runs through a bearing, L, in an arm that projects fromthe intersect-ing 6o ends of two diagonal braces, m n, that are securedto the hood E, which forms a part of the harvester, and said bearing Lis preferably formed by bifurcating the arm of the two braces m nhorizontally to form jaws that are internally concaved to conform to theshape of the gas-pipe, which jaws are held together to form the bearingsfor the gas-pipe I by suitable bolts or rivets, and either or both ofthese bolts or rivets may form the axle or axles of a roller or rollers,O, which may be interposed to facilitate the sliding of the gas pipe I,which forms a guide-bar. A lever, M, is pivoted to the brace m, and oneend of this lever is connected by a rigid link, 1), with thebinder-fran'ie through brace i, while its other end forms a handle andcarries a pawl, q, for engagement with the teeth of a rack-brace,r, oneend of which is secured to each of the braces m '72. So

The driving or packer shaft is hung from the binder-deck in the usualmanner, as shown in Fig. 8, and shifts with the binder, as is usual, andthe sprocket-wheel S, which is splined on shaft P, is prevented fromshifting with it by a spanner, T, that projects up from a standard, U,that in turn is secured to the truss l). The arms of the spanner T entera groove in the hub of the sprocket-wheel S and hold itin position abovethe driver-sprocket 0 without interfering with its revolution.

The needle-shaft (not lettered) has its hearing, as usual, in the lowerhorizontal arm of the binder-frame, and the packer-shaft has the usuallocation of thepacker-shaftin grainbinders. l

The operation of my device is very simple, and is as follows: When the.binder is to be shifted, the lever M is released by withdrawing thepawl q and moving the handle of the ICC,

lever to the right or left to draw or thrust the binder in the desireddirection, the lever M acting on link 7), which in turn acts upon theframe 11 G of the binder, the parts being centered and prevented fromcramping by the gas-pipe I and its bearing L, which bearing Ii alsosustains some of the weight of the binder and causes it to move f reel vover its lower supports.

The brace '1: extends directly from the standard 1 to the adjacent endof the pipe I. The braces 7i: extend from the pipe I, one slightlyupward to an car on the upper side of the sleeve G, and the other to alike ear on the under side while the braeej extends diagonally from thejunction of brace i and pipe I to the upper lug on the sleeve G, towhich the outer end of upper brace, 75, is attached.

Having thus il'illy described my invention, what I claim as new, anddesire to secure by 1 extending therefrom over the bi nder-deek andforming abearing, a guide-bar braced to the lander-frame and adapted toslide in said bearing, and a level-pivoted on the harvesier andconnecting it with the bimler-lranie,silhstantially as described.

2. The comlnnation, with the birider-Frame and deck, of a hood extendingfrom, the elevator-frame, braces extending, from the hood and li'orming'a bearing, a guide-bar braced to the binder-frame and adapted to slidein said bearing, and a shifting-lever pivoted to the hood and connectingit with the hind err-frame, suli)stantially as deseril. ed.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Vis- (ieonsin, in thepresence of two witnesses.
